Fault frequency information is very important in vibration analysis and reliability efforts.  This information allows the analyst to correlate vibration data to specific components in the equipment that may be in some stage of failure. Correctly addressing these failure conditions will increase equipment reliability resulting in greater uptime, increased capacity, improved product quality, better safety, [...]

Detecting rolling element bearing defects can be difficult if a few things are not taken into consideration.  First, consider how the bearing fails.  Normally one of the races will begin to fail followed by the roller/ball and then the cage.  Initially these failures do not show up at the calculated bearing fault frequencies, but at [...]

Knowing the exact bearing information for your equipment can make bearing defect analysis much easier.  However, it may not always be possible to acquire the bearing information for your equipment.  This can make it difficult to determine the bearing fault frequencies for correct analysis. It is possible to remember easy formulas to calculate the approximate [...]
